lugh, i apologise for me asking such things I knew already about, but this community faciliates a tendency in me being lazy! Without I would have probably already have made some Et2O on my own, and a good amount was also made now, costs were less then a 20th of bought one. I also knew already about the properties of DIPE regarding peroxide formation Just wanted to know about the schlenk equilibrium but figured it already out even if its not of use now anyway.

For DCM, i was talking about acidic solutions and its not really an emulsion im talking about there?

Oerlikon, your diacetylmorphine is nearly insoluble in anything beside methanol and aromatic hydrocarbons, so should be easy to figure out i guess?

Apologies for the laziness but does anyone have a nice staining protocol for c. purpurea sclerotia. I want to look a little closer at this under 100x. Thanks in advance.

Saturate strips of filter paper with 2% p-dimethylaminobenzaldehyde in 45% ethanol; air dry and store in tightly stoppered amber bottles (or keep in stoppered container in dark) which will keep them useful for several months. Put a little of the suspect substance in a few drops of ethanol (gin may do, but do a control), wet a filter paper strip in this and allow to dry. Put one drop concentrated HCl on the dried paper (don't let it touch anything). Alternatively, the powder can be placed directly on the strip and the HCl dropped on it. A violet red or violet blue spot indicates indole derivatives such as LSD. With DMT or psilocybin the color is redder. The color must be observed soon after adding the HCl since it rapidly changes.

yes because it is 1-(c6h5 so phenyl or short phen and 1- because its on 1 which is N in most cases if present, for example look at indole, then ch2-ch3 or ethyl which, because it is the last substituent in the naming of this group precisely and has then phenylgroup on its second carbon, so there a 2-.

addition: wtf is going on with the 4-? it is because it is named for for the 4- position of piperidon, because if oxygen is present too than thats primary in counting, like in phenmetrazin or such.

another name maybe could be n-(4-piperidinone)-2-phenylethylamine?

Stupid question maybe, but Ive found numerous descriptions.

What colour is anhydrous reagent grade Ferric Chloride, quality enough to use as Friedel-Craft catalyst?

Ive come across some very dark brown chloride,with flecks of caramel, but it isnt exactly what Id call green/black,(purple depending on the light) as per most descriptions Ive seen and its in the form of fine powder as opposed to crystalline.This stuff does fume somewhat when open to air. Ive attempted to further dehydrate a sample in a stream of dry HCl with no noticable colour change.

Anyone with real word experience?

BUT>>>final result is like flos grits. Assume not enough water was boiled off. Which leads to>>>

best way to dry it out?

Your question is almost incomprehensible, and it's clear your understanding of this language is minimal The best way to dry it isn't mentioned due to the expense involved The attached documents from the Organic Syntheses website and Wikipedia explain the relevant facts very well You need to reread the threads you're quoting from many more times, and start looking for more sources of information online The information you seek is available in other languages Bright Star has a PhD from a prestigious university, and his method to mdma isn't exactly crude as it has worked for thousands of members The end results from the effort applied

admitted that comprehension isn't a strong suit. Need to get the hands dirty to learn anything.will review the attachment, thank you kind sir.

2nd batch turned out much less "wet"...let it boil longer. After that, had a chance to read lugh's attachment, interesting indeed. I think the key words left out of Rhodi's photo essay were "until crystals begin to form on the surface". Although, now looking back, they can be seen in the picture.

So it would appear that Brightstar method=crude, the rhodi method pretty darn close, and the winner would be organ syth vol 1 pg 347>>>

What is the approximate time course required to go from aldehyde->aldoxime->hoffmann ?

Consider you have to do the beckmann rearrangement before the hofmann rearrangement can take place. About the time, i think it can be done in less than 2 two days if every reagent is available, but i dont know for sure.

Yeah you can do it within 2 days if you want, first step 4/6 hours, second step 6/7 hours and hofmann about 2 hours in total.

Now a question from me: How much solvent do you need to get your freebase out of the hofmann rxn? Is there a simple ratio when you use IPA?

as a rule of thumb, use 2 times a tenth of mother liquor volume and the third time one part on twenty suffices. Just let every layer sit long enough, and avoid an emulsion.Also, dont use IPA, better suited would be hexane or toluene/xylene, IPA has to be salted out afterwards otherwise its completely miscible with water.

Thanks! So 1:10 xylene:freebase and then 1:20 xylene:freebase would be fine am I right? With xylene the dog wouldn't get trouble gassing the hell out of it with HCL right?

Re: Short Question Thread 2.0

Jon is the best. boil under vaccum in Salt/water bath (106ºC) until your product smoke inside the flask than turn off all and choose your way to recover it. In this way you can avoid chloroform but If you heat more than 106º chloroform is required.
